I think it very unlikely a Ford dealer is offering to install the wrong oil in a PowerStroke. More likely something has been misunderstood or lost in translation.
I don't. I would bet it's what they have in bulk and make the most profit on. This is just one of the reasons why I do my own servicing. OP, I would go with what the manual says, and stick with synthetic; it will cost a few bucks more but well worth it especially if you plan on keeping the truck for a long time. I also only use OEM filters on all of my vehicles.
